Yes! It's called STEEMPUNKNET and it's a steampunk oriented RPG game where you can find loot, earn xp and duel other players whilst surfing on Steemit!

Check out @steempunknet ! It's a chrome add on and it's currently in beta and being developed and expanded. Lots of cool features planned for the future! I think it's very promising, especially if they go the route of unique items, if you look at what CryptoKitties did. Do check it out, it's a cool project (and then come fight me!! rawr )

Haha challenge accepted!! @pandorasbox
